Ar/Ar data are reported from minerals and rocks that were collected as part of a mineral resource investigation of the Tonopah, Divide, and Goldfield districts in Nevada. Data are reported from 92 samples and associated standards from eight separate neutron irradiations in the Denver USGS TRIGA reactor, including separated mineral grains and whole rocks. Data were collected by infrared laser heating of irradiated samples, either incremental heating or fusion, and analysis by multi-collector mass spectrometry. The reported data have been corrected for blanks, radioactive decay, and interfering nucleogenic reactions associated with sample irradiation.

Collection contains original copies of geophysical well logs and records from 14210 wells drilled for uranium exploration and evaluation in New Mexico. Most of these are one-of-a-kind and not available elswhere. The collection has been 90% catalogged. A listing is available upon request.

location plats, completion reports and driller's logs for oil and gas wells drilled within West Virginina. Approximately 25,000 of the early, pre-regulation wells only have location platsphysical logs are filled in 21 legal-sized filing cabinets

The SDF or Stratigraphic Data Files are a collection of paper drill records from thoughout Pennyslvania organized by 7.5 minute quadrangle. It is a prime source of subsurface lithology. Portions have been entered into the USGS NCRDS database.This is a Topo/geo resource which does not belong to any one staff member.The last estimate of the collection was 31,500 done is 1987. A better estimate is currently underway. The main use for the collection is in-house reference and research by PaGS staff.

Collection of reports containing from one to up to several hundred pages and water well files related to the MX Missile Project of the late 1970s and early 1980s. The collection is in 2 4-drawer filing cabinets. The geologic/hydrologic reports are kept at the NBMG, and some years ago, the cultural reports were sent to the Nevada Historical Society. The "Amount" is based on the number of reports and files listed on a typed index that may need revision. MX Files The area covered by the project is part of eastern and central Nevada. The collection is indexed by a typed list of reports and files in a binder, which needs to be reviewed against what is in the collection. The collection may be considered to become part...

3296 sidewall cores from 124 oil & natural gas exploration and development wells in New Mexico. This collection contains 3,296 sidewall cores from 124 oil & natural gas exploration and development wells in New Mexico. Although this collection is growing, there is a limit to the volume of new acquisitions we can accept because of very limited storage space.

This collection includes unpublished maps in Arizona, which were compiled for uranium resource assessment, conducted in 1980. Collection includes National Uranium Resource Assessment (NURE) compilation project maps. This collection has not yet been cataloged. Please contact the Arizona Geological Survey to inquire about this collection.

Hand samples collected from outcrops during field work by survey staff members and students. Hand samples were collected in the filed by various staff members and students. Only partially organized and cataloged in several different digital and paper databases. Metadata content of databases is not uniform. There are approximately 6500 samples cataloged in various paper and digital databases and several thousand samples that have yet to be either organized or cataloged. This collection is stored in trailers (mobile homes) and container units and is currently not fully cataloged, organized or accessible.

The Montana Bureau of Mines and Geology (MBMG) Mining Property File collection was amassed over the years through private and industry donations of engineering and geologic reports, pictures, correspondence, news clippings, and production information. The collection presently contains over 4,400 property-specific files (records). The physical files are organized first by Montana county and then by mine or project name. Files may contain information related to a particular mining claim, a collection of claims, or a mining exploration project. Metadata describing each record includes property name, location (county, historical mining district, township, range and section), georeferences (latitude and longitude), and...

Website of various Nevada geothermal resource information, which contains 227 geothermal site descriptions and related digital maps, photographs, and information sources. Geothermal Resources of Nevada Two NBMG geologists spend part of their time keeping up this database. Aside from the list of 227 geothermal sites which are linked to site descriptions and maps, the website also contains an interactive map based on NBMG Map 141, "Nevada Geothermal Resources," which shows locations of all significant occurrences of geothermal water in Nevada of which more than 300 are linked to site descriptions and/or databases accessed by mouse clicks; links to the files used to create the interactive map; a list linked to 82 large-scale...

Minnesota Geological Survey maintains a database of over 4000 rock property values that are needed for geologic mapping, and are similarly used by partner agencies and by industry to support exploration. These data thus help relate geophysical anomaly signatures to probable rock types, and provide constraints on the use of anomaly data as a tool for mapping and for modeling geology at depth. Most of the density and magnetization data contained in this database were acquired over the last two decades as part of on-going activities. Paleozoic samples were collected from Iowa and included in the database because they provide a representative suite of data for rocks present, but not widely exposed in Minnesota. Additional...
